An anonymous Internet communication system based on a distributed network. Tor is a toolset for a wide range of organizations and people that want to improve their safety and security on the Internet. Using Tor can help you remain anonymous while Web browsing, instant messaging, using IRC, SSH, or other applications which use the TCP protocol. The Tor network takes a random pathway through several servers that cover your tracks so no observer at any single point can tell where the data came from or where it's going. Tor also provides a platform on which software developers can build new applications with built-in anonymity, safety and privacy features.
Tor was developed is supported by the Electronic Frontier Foundation.
